Yes, that`s correct, I have now study the camsensor and it`s places on the high pressure fuel pump pulley, in the left front of the engine. I did the measurement on the B connector/ engine ECU so I don`t looked after sensor physical. Seems that I have to remove some mecanical parts incl. timing belt and check out timing/ belt and pulleys.

Andy: Darren have already give me the answer about cam/crankshaft. I hoped that the camsensor was located close to the cam physical so I could see the time between those pulleys. See text over, thanks.

Do you not feel if it was a timing fault you would get a cam / crank sync fault. if you feel it is disconect cam sensor and try starting engine, ive diagnosed many vectra diesels this way. just a thought.

if an injector has already been out then take it out again & do a proper compression test.........this will show a true compression pressure compared with a relative one, and lead you to a possible timing issue, the relative test just shows odd ones out.

Otherwise tear it down & just check it once & for all.

The injector seems to be firing, but seeing as you are only on a time base to see just one event then we can only assume it is firing once.........i did ask for more time on screen !
